APPLICATION METHOD FOR M52743SP
CLAMP PULSE INPUT
Clamp pulse width is recommended
above 15kHz, 1.0µsec
above 30kHz, 0.5µsec
above 64kHz, 0.3µsec.
The clamp pulse circuit in ordinary set is a long round about way,
and beside high voltage, sometimes connected to external terminal,
it is very easy affected by large surge.
Therefore, the Fig. shown right is recommended.
